Flash Forge Creator Dual / PowerSpec 3D Pro Carriage Mk 5

thingiverse

This is the Mk 4 Version of my Replacement Carriage for Flashforge Creator Pro Dual-Extruder Printers. Instructions: Update 1: My Initial Mk 1 Design Was Extremely Challenging to Assemble Due to Interlocking Parts. Tight Tolerances Led Me to Rethink and Redesign, Now Using Long M3 Bolts to Secure the Main Body, I Also Revised How the Y-Axis Belt is Secured from a Separate Piece to an Integrated Zip-Tie Channel. Update 2: My Mk 2 Design Printed Well But Experienced a Few Issues. The Y-Axis Belt Kept Rubbing Against the Bottom, So I Enlarged the Channel for the Bottom of the Y-Axis Belt and Repositioned Bolt Holes with Countersinks to Accommodate Common M3 Hex Socket-Head Bolts. Additionally, I Addressed Strip-Tie Channel Misalignment Issues. Update 3: Although Mk 3 Printed Well, Multi-Piece Designs Can Cause Slight Misalignments in Bearings, Prompting Me to Create a Single Part Design That's Printed Inverted with Support on the Build Platform. This Eliminated the Need for Bolts, and I Secured the Y-Axis Belt Using Two Strip Ties at Its Center. For Added Strength and Reduced Weight, Honeycomb Manual Infills Were Integrated into Cross-Beam Sections. Update 4: The Mk 5 Design Allows Adequate Room Behind the Heater Blocks and Replaced the Difficult-to-Tighten Zip-Tie Y-Belt Clamp with a Securing System Requiring Two M3 10mm Bolts. This Model Incorporates Additional Changes, Including the Use of Thicker M3 15mm Bolts to Secure Heat Spreaders Due to Cross-Beam Modifications. Despite Some Cleanup from Support Material Being Required, Assembly and Fitting Go Smoothly. I Successfully Installed and Printed With This Version Using ABS, a 2.0mm Layer Height, and 30% Infill at the Experimental Stage; Support Is Required When Printing This Model Inverted for Optimal Results. The Development Process and Original Files for Mk 1-4 Can Be Viewed Within a Zipped Archive on Your Own Request. Please Note: This Design Remains in Test Phase and I Encourage Any Input or Comments. Future Developments Include Enhancing the Print Carriage to Produce a Lightweight and Thin Model. In Time, My Aims Are To Base a Full Bowden Extruder and Interchangeable Laser Etcher Print Head Upgrades on this Carriage Replacement.
